GitHub Actions OIDC

IAM concepts
GitHub Actions OIDC is a workload identity mechanism that allows GitHub Actions CI/CD workflows to authenticate to cloud providers and external services using short-lived, cryptographically signed tokens instead of stored secrets. The workflow proves its identity through an OIDC token issued by GitHub, which cloud platforms like AWS, Azure, and GCP can verify and exchange for scoped access credentials. It eliminates the need to store long-lived cloud credentials as GitHub secrets.

Governance

IAM concepts
Governance sets the policies and controls for who has access, why they have it and whether that access remains appropriate over time.

Granularity

Security concepts
Granularity refers to the level of detail and precision an access control system can apply when defining permissions. A granular access model allows organizations to specify exactly which identities, human or nonhuman, can perform which actions on which resources, under which conditions.

Generative AI

AI/MCP Concepts
Generative AI refers to systems that can create new content, such as text, images, code, or audio, based on patterns learned from large datasets. Unlike traditional predictive AI that classifies or forecasts, generative AI produces original outputs in response to prompts or contextual inputs.

Group Policy

IAM concepts
A feature used in IAM systems, especially in Active Directory environments, to manage and configure the settings of user and machine identities across an organization.
